Everything you need to know about CS2 knives: Doppler phases explained, Case Hardened blue gem values, float impact on price, and the most valuable knives ranked.
The official knife and glove drop rate is approximately 0.26% — roughly 1 knife per 385 cases opened. This hasn't changed since CSGO and remains the most coveted unboxing outcome in Counter-Strike 2.
| Rarity | Drop Rate | Cases to Open (Avg) |
|---|---|---|
| Covert (Red) | 0.64% | ~156 |

Doppler is the most valuable and confusing knife finish. Here's how to tell them apart:
| Phase | Colors | Value Multiplier |
|---|---|---|
| Phase 1 | Black + Dark Red/Pink | 1.0x (base) |
| Phase 2 | Black + Pink/Purple | 1.1-1.3x |
| Phase 3 | Black + Blue/Green | 1.0-1.1x |
| Phase 4 | Black + Dark Blue | 1.1-1.2x |
| Ruby | Pure Red | 4-8x |
| Sapphire | Pure Blue | 5-10x |
| Black Pearl | Dark Purple/Black | 3-6x |
How to check: Use FloatDB or CS2 inspect tools to see the pattern index and paint seed. Ruby/Sapphire/Black Pearl have specific pattern ranges that separate them from standard phases.
Case Hardened skins have randomized blue and gold patterns. A "Blue Gem" is when the playside is mostly blue. The amount and placement of blue determines value:
Float determines wear. The difference between 0.01 and 0.06 on a Doppler knife can be $500+.
| Wear | Float Range | Price Impact |
|---|---|---|
| Factory New | 0.00 - 0.07 | Highest value. Low float FN (0.00-0.01) commands premium |
| Minimal Wear | 0.07 - 0.15 | 20-40% less than FN |
| Field-Tested | 0.15 - 0.38 | 40-60% less than FN |
| Well-Worn | 0.38 - 0.45 | 60-80% less |
| Battle-Scarred | 0.45 - 1.00 | Lowest value. Some collectors want max BS for meme value |
Slaughter finishes can have heart or diamond shapes on the blade. A centered heart or diamond can double the knife's value. Check both playside and backside.
Marble Fade knives with a "Fire & Ice" pattern (red and blue separate, no yellow) are worth 3-5x more than a standard Marble Fade. Most commonly found on Karambits and Talon Knives.
Centered, large webs on the playside significantly increase value. Combine with low float (Factory New) and you have a collector's item worth 2-4x market price.
The Karambit Case Hardened Blue Gem pattern 387 is the rarest, worth $100,000+. Doppler Sapphire and Ruby phases are the next tier at $5,000-15,000.
Factory New (0.00-0.07) commands the highest prices. Minimal Wear is 20-40% cheaper. Field-Tested and below lose 50-80%. Ultra-low float FN (0.00-0.01) carries a significant premium, especially for Doppler and Crimson Web.
The Karambit Doppler Sapphire (FN) at $10,000+ and the Karambit Case Hardened Blue Gem at $100,000+ are the most valuable individual CS2 knives unboxable from cases.
